Original application filed January 7, 1905, Serial Nok240.003- Divided and this application filed January 9, 1906. seas To all whom it may concern;

Be it known thatI,- PAUL Ter nce. Sm-

vER'r, a citizen of the German Empire,'and a resident of Dresden, Germany, have invented certain new and useful Improvements in Machines for Forming Glass Articles, of which the following is a specification.

The invention relates to an apparatus "for blowing or otherwise forming glass articles from a plastic glass maslf fsnspiindedfioma carrier. n

It rovides means for'corivenientl bringor forming it as desired and supportin and removing the finished or partlyfinis ed article.

' It further rovides various combinations of arts, whic will be set forth in the claims.

11 the drawings, Figure 1 is a vertical elevation, partly in section, of a glass-forming machine embodying my invention. Fig. 2 is a-section through the line C D, Fig. 1.

1 designates a carrier consisting of a frame which may have any desired form and which, as shown, is suspended. from the shaft 2, r0- tatably supported on a frame 3. The rotation of the shaft is effected by means of a worm-gear 4, which is driven by any suitable motor. (Shown as an electric motor 5.) The frame 3 is capable of vertical motion in the main frame 6 of the machine and is suspended by a cable 7, which runs over a winch 8 and carries at its free end a suitable counterpoise 9. The winch ,8 may be rotated by means of a motor 10, whereby the slide-frame 3 and the carrier-frame 1 are raised and lowered as desired.

.11 designates a mold into which the molten oured, which mold may be provided wit Immediately beneath the carrier 1 is a heating-chamber 18, provided with covers 19, carried on wheels 20, and in the form of the invention shown capable of being retracted in both directions b a system of levers 21 22 23 24 25, connecte with the worm-gear 26, actuated by a motor 27.

frame 6 is a bracket 50, adapted to carry the mold 11 and by its rotation to swing the mold either into or out of the vertical path of the carrier 1. Pivoted to another of the uprights of the machine-frame 6 is a second bracket 53,, to which is hinged a receptacle a cooling-chamber 15, as shown.

Pivotally mounted on one of the uprights of the machine.

ror the glass article in recess-of formation or after it is completely ormed, which recep tacle consists of a framework or cage 54, se cured on a plate 55. It is of course understood that this bracket53, like the bracket 50, is adapted to be swung into and out of the path of the carrier 1. A third bracket 1 58 is rotatabl-y mounted on one of the upcarrier-frame ist en. caused to adhere to'the 1 periphery of the cast mass. In a revious application, Serial No. 240,003,filed anuary 7, 1905, of which case this ice. division, I have claimed the process of supporting the glass mass in the mold until it was sufi'ciently cooled to prevent its dropping considerably out of ahorizontal plane when it wasiiitedtherefrom by the raising of the carrier." It is of course unimportant whether this prelimi-- nary cooling is adopted in the present inven' tion or not. .Whenever desired," the carrier:

1 is raised so as to remove the glass mass 1 1- from the mold 11. be swung out of the path of the carrier and the glass mass be permitted to elongate by its 1 he bracketSO may then own gravity, as desired. It may of course at any time be lowered into the heating-charm ber. 18 for further extension or treatment.

Where a cylinder is being formed, as in'the manufacture of plate-glass, the bracket 53 may at any time be turned into the path of i the carrier 1, the latter being raised for this purpose and the cylinder 56lowered into the framework 54 on the bracket 53. It will be seen that this supporting-frame, consisting of the cage 54 and plate-55, is hinged at its outer edge to the end of the bracket 53, so that it may be tilted for the convenient'removal of the gylinder 56. The plate 54 may be provide 55 for securing its return to its horizontal position. Where it is desired to form the glass mass 14 in a rno1das,-e. g., to form a vase.the bracket 58, carrying the mold 59, may be swung intothe path of the carrier 1,

with an arm carrying a counterweight"
